“…Such differences in properties of the initial metals could severely affect the quality of the joint. For example, it weakens the mechanical properties like toughness by facilitating the formation of cracks [10]. Moreover, different problems may occur in the austenitic side and/or ferritic side of welded region which experience high thermal cycles during the welding.…”

Dissimilar joints of AISI 430 ferritic and AISI 304L austenitic stainless steels were produced by friction stir welding process. A sound and defect-free joint was obtained at 1 mm tool offset towards the ferritic sample located in the advancing side, and at rotational and welding speeds of 560 rpm and 50 mm/min, respectively. The XRD measurements revealed the presence of approximately equal volume fractions of ferrite (51%) and austenite (49%) phases in the stir zone (SZ). The formation of low-angle grain boundaries through the occurrence of dynamic recovery along with the presence of shear texture components in both constituent phases of ferrite and austenite in the SZ approved the occurrence of continuous dynamic recrystallization throughout the evolved microstructure. Moreover, microstructural observations showed the formation of necklace structure through the microstructure of ferrite in the SZ. Taylor map approved the strain localization in the ferrite phase. Micro-hardness measurement indicated that the hardness value is increased in the SZ. The result of tensile test showed that fracture occurred from less ductile ferritic base metal.

“…The distribution of points between W 1 and W n given in equation (5) ensures the total energy in the material in the plastic area is represented equally during the search of optimal values of the AF material parameters ( Figure 2). The estimated yield stress of the material R 0e can be established e.g.…”

“…It ensures high creep and corrosion resistance, oxidation stability and good mechanical properties for a competitive price as compared to austenitic stainless steels, which have been traditionally used in high temperature environments. 3,[5][6][7][8] Titanium stabilisation additionally improves its weldability and decreases the recrystallisation rate at high temperatures. However, such materials operating under variable mechanical and thermal loadings will still be subjected to thermomechanical fatigue, due to repeated phases of start-up, interchanges of full and partial load, and shut-down.…”

The four most commonly used optimisation methods for linking the material parameters of an exponential Armstrong–Frederick and a power Ramberg–Osgood model are compared for given cyclic stress–strain curves of a ferritic stainless steel EN 1.4512. These methods are the damped Gauss–Newton method, the Levenberg–Marquardt method, the Downhill Simplex method and a genetic algorithm. Globally optimal material parameters are obtained by parallel searches within the methods. The methods are tested for cyclic curves at 20 ℃, 300 ℃, 650 ℃ and 850 ℃. The optimal values of material parameters and R2 values are comparable, whereas the search paths, the numbers of steps to reach optimal solutions and the processing time of the methods differ.

“…It has been observed that the welding speed is the most influencing parameter for weld bead width, whereas the penetration and reinforcement have been influenced by the wire feed rate. Ghosh et al [23] executed metal inert gas welding and joined two dissimilar materials, namely AISI 316L austenitic stainless steel to AISI 409 ferritic stainless steel. The Taguchi orthogonal L 9 array has been implemented for experimentations, and the influence of various welding parameters namely nozzle to plate distance, welding current, and gas flow rate, has been examined on yield strength and ultimate tensile strength of the welded materials.…”

The present study aims to highlight the effect of the governing variables in regulated metal deposition (RMD™) on the mechanical properties and weld quality of low alloy steel. Current, voltage, and gas flow rate have been considered as main (RMD™) parameters, whereas heat-affected zone, depth of penetration, bead width, and bead height have been taken into account as welding performance characteristics. Signal to noise has been utilized in order to determine the optimal welding parameters, while analysis concerning the significant level of determination has been assessed using analysis of variance. Furthermore, the exploration of principal component analysis and combined quality loss concept integrated with the Taguchi method has been introduced to assess the favorable welding condition. The optimal favorable machine combination has been obtained as current = 100 A, V = 13 V, and gas flow rate = 21 L/min using both the methods.
